Arrow rest accessory for archery bow

ABSTRACT

An arrow rest accessory for mounting on an archery bow and aiding in the accurate and precise guiding of arrows shot therefrom, in the form of a laterally-projecting helical spring member, against which the side and bottom portions of the arrow shaft rest, for absorbing the shock imparted to the bow following arrow release. The spring member is affixed to the free end of a flexible arm of spring steel whose other end is secured to the handle riser portion of the bow by an adjustable mounting which permits independent adjustment of both the vertical and lateral positioning of the rest relative to the bow.

3 Claims, 4 Drawing Figures ARROW REST ACCESSORY FOR ARCHERY BOWBACKGROUND OF THE INVENTION This invention relates to an arrow rest foran archery bow for absorbing the shock occasioned by the sudden releaseof the arrow and thereby improving accuracy in flight and closergrouping of arrows shot in target competition.

ln archery contests, as well as in bow hunting where accuratemarksmanship is important, precise control of the various parametersaffecting the accuracy of arrow flight is crucial. Accordingly, variousmechanical aids have been developed for use by archery marksmen,including optical bowsights, stabilizers for absorbing the shock ofarrow release, rope releases, etc., all with the objective of improvingaccuracy. To the same end various arrow rest bow attachments have beendeveloped in the past, as an alternative to the use of the shelf formedintegrally in the bow, to reduce the shock and vibration imparted to thebow, and thus to the arrow, upon the latters release.

SUMMARY OF THE PRESENT INVENTION The present invention is directed to animproved form of arrow rest accessory, adapted to be used with a widemultiplicity of bow designs and sizes, which materially lessen shock andimpact on the bow and thus on the arrow following its release. The arrowrest of the present invention is in the form of an accessory adapted tobe mounted on the handle riser portion of the bow and provides anenergy-absorbing lateral and vertical support for the forward portion ofthe arrow shaft. The arrow rest has independent adjustment means forpermitting its ready vertical and lateral positioning relative to thebow, as desired. Improved accuracy, resulting from the absorption andconsequent minimization of the shock impact to the bow following arrowrelease, is achieved.

It is accordingly a principal objective of the present invention toprovide a new and improved arrow rest accessory for an archery bow whichminimizes the shock imparted to the bow following arrow release.

It is a principal feature of the present invention to provide an arrowrest accessory for mounting on an archery bow which is provided withmeans for independent adjustment of the vertical and lateral positioningof the arrow support rest relative to the bow.

The foregoing objectives, features and advantages of the presentinvention will be more readily understood upon consideration of thefollowing detailed description of the invention, taken in conjunctionwith the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a pictorial view showing anembodiment of the arrow rest of the present invention installed on anarchery bow.

FIG. 2 is an enlarged side view showing details of the arrow rest of thepresent invention.

FIG. 3 is a top view of the arrow rest.

FIG. 4 is an exploded view of the arrow rest.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. I shows an archerybow of conventional design on which is mounted the improved arrow restof the present invention against which the shaft of arrow 15 rests priorto and during release of the bow string. As shown in the detailed viewsof FIGS. 2-4, the arrow rest 20 is comprised of a cantilevered armmember 25 of thin flexible resilient metal, such as spring steel, whichis disposed between the arrow shaft and riser portion of the bow andaligned substantially colinear with the arrow shaft. The fixed end ofthe arm member 25 is secured to a mounting means 27, 28, details ofwhich will be described later, using a pivot set screw 30 which, whenloosened, permits angular adjustment of the arm relative to the mount.The free end of the cantilevered arm member 25 is provided with alaterally-projecting helical spring 29 of two or three coil turnssecured thereto at 35, either by spot welding or soldering, andterminating in a free coil end 29a. The coil end 29a is formed bystraightening a portion of the arcuate coil end of the spring and isarranged to align substantially horizontally. The finger-like coil end29a is directed toward the forward end of the arrow shaft 15 and servesas a bottom support for the shaft, with the coiled turns of the spring29 serving as a lateral abutment for the shaft.

Turning now to the mounting for the arm member 25, as previouslydescribed set screw 30 provides a lockable pivot pin connection of thearm to the mounting means formed by the pair of elements 27, 28. Theright-angle flange 28 is secured to an appropriate location on thehandle riser portion of the bow 10 using a suitable fastener means, suchas screw 32. The leg portion of the flange 28 which extends across theinner face of the bow is provided with a horizontal keyway groove whichmates with a corresponding dovetail formed in slidebar element 27, thekeyway combination providing a laterally slideable mounting for thelever arm 25. Thus the lateral position of the rest relative to the bowand transversely to the arrow shaft is adjustable and lockable bysecurement of the set screw 31 which, when tightened, fixes the positionof bar 27 along the keyway groove of flange 28. (As an alternative toelement 28 of the combination forming the mounting means for the arrowrest, an appropriate keyway groove could be formed integrally in theinner face of the riser portion of the bow 10 so as to provide thechannel within which the slidebar 27 can be laterally positioned andsecured.)

By reason of the two degrees of adjustment, as indicated by thearrowheads in FIGS. 2 and 3, provided by (l) the pivot screw 30angularly positioning the end of the lever arm 25 against the washer 33and slidebar 27, and (2) the set screw 31 securing the lateral positionof the slidebar 27 relative to the flange 28 affixed to the bows handleriser, the position of the operative support portion of the arrow restcan be readily and independently positioned both vertically andlaterally relative to the bow.

' In use, the release of the bow string and the consequent suddenforward acceleration of the arrow would ordinarily produce a severeshock to the handle riser portion of the bow against which the arrowshaft rests. This sudden impact would, in the usual case, induce amomentary vibration of the bow, which movement, even though minute, whenretransmitted to the arrow would likely cause deviation in its intendedflight path. However, with the use of the rest of the present invention,the shock impact generated by the arrow upon its release is largelyabsorbed in the spring portion 29 and the cantilevered arm member 25,both of which compress under impact but, because of their resilientnature, act as mechanical energy absorbers and do not transmit anysubstantial shock or vibration to the bow to which they are coupled.Accordingly, the absorption of this impact by the rest 20 allows thearcher to maintain the bow rock steady following release of the arrow,thus eliminating any deviation in the arrows flight which mightotherwise be caused by slight movement or oscillation of the bow inresponse to the shock of arrow release.

The terms and expressions which have been employed in the foregoingabstract and specification are used therein as terms of description andnot of limitation, and there is no intention, in the use of such termsand expressions, of excluding equivalents of the features shown anddescribed or portions thereof, it being recognized that the scope of theinvention is defined and limited only by the claims which follow.
